Title: Track jump circuit
Inventor: NAKANE HIROSHI
IPC: G11B7/085
Filed: 1987-03-31
Abstract: PURPOSE:To shorten a time required for track jump by controlling an integration compensating circuit to be in an off-state if a distance signal from a distance signal generation means is supplied to a shifting means. CONSTITUTION:If the objective retrieval of an information signal is requested by an external operation, namely if the track jump is requested, an arithmetic circuit 3 sets a switch 17 to the off-state, namely, the integration compensating circuit 7 to the off-state. At that time, a component which a comparator 16 outputs and whose difference is between a voltage signal from a reference voltage generation circuit 15 and the voltage signal from an integrator 14 is supplied to a slider motor 8 through an adder 12, an adder 6 and the integration compensating circuit 7. Since the integration compensating circuit 7 at that time is set to the off-state, off-set in track jump due to the dynamic range of the integration compensating circuit 7 does not occur. Thus, a pickup 2 speedily shifts to the objective retrieval position with driving the slider motor 8.

Title: Dot serial printer
Inventor: YAMASHITA YOSHIMI
IPC: B41J25/308
Filed: 1991-04-11
Abstract: PURPOSE:To obtain a satisfactory print quality by detecting a change in the thickness of a sheet always at the right and left of a printing head and maintaining a position for the printing head to the sheet to be fixed constantly in comliance with a change in the thickness of the sheet. CONSTITUTION:A sheet 2 is wound around a platen 1, and is printed using a printing head mounted on a carrier 8, if this carrier moves horizontally along a guide shaft 9. On the other hand, if sheet thickness detection rollers 5A, 5B, always pressed to the sheet 2, move laterally due to a change in the thickness of the sheet, a sheet thickness detection part 6 detects the movement. This detection signal is transmitted to a printing head position control part 7 by a sheet thickness data transfer part 11. The printing head position control part 7 transmits printing head position data to a printing head position movement part 4 through a position transfer part 10. A printing head position movement part 4 moves the printing head 3 to a position corresponding to the sheet thickness based on the printing head position data.

Abstract: PURPOSE: To prevent the chatter in input and output and improve the feeling of steering on the basis of a smooth proportioning characteristic, by setting phase differences among planet gears to raise the total intermeshing ratio.  
     CONSTITUTION: A sung gear 11a with 42 teeth, a ring gear 14a with 66 teeth and three planet gears 12A, 12B, 12C are provided. An angle difference of 90° is set between the planet gears 12A, 12B clockwise in Fig. An angle difference of 210 to 240° is set between the planet gears 12A, 12C clockwise in Fig. The intermeshing phase is inverted at every 30° on the basis of the planet gear 12A. The phase of the gear 12B is inverse and that of the gear 12C is intermediate with regard to the reference gear 12A. Therefore, the intermeshing of the gears 12A, 12B, 12C is overlapped by the phase differences.

Title: Dividing arithmetic unit
Inventor: MIYOSHI AKIO
IPC: G06F7/535
Filed: 1987-03-31
Abstract: PURPOSE:To eliminate excess operations and to increase the operation speed by discriminating whether overflow occurs or not in the end of dividing operation. CONSTITUTION:After division is repeated a prescribed number of times to obtain a quotient, contents of an overflow instructing circuit 7 are checked. The one-bit flag held in the circuit 7 indicates whether the first operation result in an ALU 4 is negative or not. One bit outputted from a division result generat ing circuit 5 at the time of terminating a first operation in the ALU 4 is finally shifted to the circuit 7 by a prescribed number of shift operations in a register 2 and reflects on this flag as the result. Consequently, when the flag is '1', A>=B is satisfied at the first time and final data C obtained in the register 2 is not a correct quotient, and the overflow processing is performed. When the flag of the circuit 7 is '0', data C is a correct quotient.
